電容電機(jī) YY78系列
電容運(yùn)轉(zhuǎn)電機(jī)由定子組件、轉(zhuǎn)子組件、支架組件組成。定子接到交流電網(wǎng)，依靠電磁感應(yīng)作用使轉(zhuǎn)子產(chǎn)生感應(yīng)電流，產(chǎn)生電磁轉(zhuǎn)矩，從而達(dá)到轉(zhuǎn)換機(jī)電能量的目的。當(dāng)電流流入定子繞組時(shí)，電流分別在定子組件的主繞組與副繞組中產(chǎn)生兩個(gè)電流回路，由于副繞組的電容的影響，副繞組的電流超前主繞組的電流約90度的相位，從而在氣隙中將產(chǎn)生一旋轉(zhuǎn)磁場(chǎng)，并以同步轉(zhuǎn)速在旋轉(zhuǎn)。當(dāng)旋轉(zhuǎn)磁場(chǎng)切割轉(zhuǎn)子導(dǎo)體時(shí)，將在其中產(chǎn)生感應(yīng)電勢(shì)，電勢(shì)的方向用右手定則來判斷。由于轉(zhuǎn)子繞組是短路的(鑄鋁轉(zhuǎn)子)，在轉(zhuǎn)子導(dǎo)體中便有電流流過，轉(zhuǎn)子導(dǎo)體中的電流與氣隙磁場(chǎng)相作用而產(chǎn)生電磁轉(zhuǎn)矩，轉(zhuǎn)矩方向用左手定則來判斷。它與旋轉(zhuǎn)磁場(chǎng)同方向，在電磁轉(zhuǎn)矩作用下，轉(zhuǎn)子以轉(zhuǎn)速(小于同步轉(zhuǎn)速)順著磁場(chǎng)方向旋轉(zhuǎn)。
The capacitor running motor is composed of a stator assembly, a rotor assembly and a support assembly. The stator is connected to the AC power grid, and the rotor generates induced current and electromagnetic torque by electromagnetic induction, so as to achieve the purpose of converting the electromechanical energy. When the current flows into the stator winding, the current generates two current loops in the main winding and the secondary winding of the stator component respectively. Due to the influence of the capacitance of the secondary winding, the current in the secondary winding is about 90 degrees in phase ahead of the current in the main winding, so that a rotating magnetic field will be generated in the air gap and rotate at synchronous speed. When the rotating magnetic field cuts the rotor conductor, an induced potential is generated in it, and the direction of the potential is judged by the right hand rule. Because the rotor winding is short-circuited (cast aluminum rotor), there is current flowing in the rotor conductor, and the current in the rotor conductor acts with the air gap magnetic field to produce electromagnetic torque, and the direction of torque is judged by the left-hand rule. It is in the same direction as the rotating magnetic field, and under the action of electromagnetic torque, the rotor rotates in the direction of the magnetic field at a speed (less than the synchronous speed).
